5.54 g (0.05 mol) of vinylphenol, 5.47 g (0.04 mol) of tert-butyl methacrylate, 2.37g (0.02 mol) of 2-vinylnaphthalene and 0.8205 g (5 mol %) of AIBN were charged into 50g (1.7 M) of toluene. After the mixture was stirred at 80° C. for 11 hours, hydroquinone was added and the polymerization was stopped. Toluene was evaporated by an evaporator to prepare a THF solution, and reprecipitation was repeated using cyclohexane. The polymer thus refined was dried in a vacuum baking oven at 40° C. for 14 hours. There was obtained a polymer having a molecular weight of 12,000, a degree of dispersion of 1.87 and a vinylphenol:tert-BuMA:vinylnaphthalene ratio of 52:43:18.
